DJI AS2 Speaker – aerial loudspeaker for DJI Matrice 5T
DJI AS2 Speaker is an aircraft-mounted loudspeaker installed beneath a drone to deliver voice announcements and instructions from the air. It is intended for search and rescue teams and other professional operators who need to communicate with people during operations. Exclusively compatible with DJI Matrice 5T, it combines several audio broadcast methods with an integrated warning strobe.
35 W power and up to 400 m effective broadcast distance
Maximum power is 35 W, with a maximum sound level of 120 dB at one meter. DJI specifies an effective broadcast distance of up to 400 m. Sound level and distance figures were measured in a laboratory at 25 °C. Actual performance depends on factors including audio source, software version and surrounding conditions, so maximum broadcast distance does not imply equal speech audibility in every environment.
Live voice, recordings and text-to-speech
DJI AS2 Speaker supports real-time voice broadcasting with echo suppression, recorded announcements, imported audio files and text-to-speech. Imported media can be transferred and played simultaneously. Loop playback is also supported, allowing an announcement to repeat without being spoken again each time.
Live broadcasting uses the remote controller microphone. DJI recommends speaking close to its upper microphone area at a steady pace. In DJI Pilot 2, starting and stopping real-time broadcasting can be assigned to customizable remote controller buttons for quick access during operations.
Five-color strobe and compact housing
An integrated strobe light offers red, blue, green, white and yellow illumination. A single accessory therefore combines voice broadcasting with visual signaling. It weighs 194 g and measures 96 × 70 × 66 mm in length, width and height. Operating temperature ranges from −20 to +50 °C, and ingress protection is rated IP55.
Installation and use with a spotlight
Installation involves inserting the speaker’s USB-C connector into the corresponding aircraft port and securing the mounting screws. Press the connector firmly into place to ensure a secure seal for water resistance. After installation, connect to the internet, activate the speaker and calibrate the aircraft compass as prompted in the app. Install the latest firmware when an update is requested; an installed speaker receives firmware updates alongside the aircraft.
DJI AS2 Speaker can be used with a separately sold DJI AL2 Spotlight. When fitting both accessories, install the spotlight first and the speaker afterward. This enables lighting and voice broadcasting on the same aircraft.
Important operating limitations
Installing the speaker affects aircraft propulsion performance and flight time. DJI recommends using it primarily for human speech and avoiding single-frequency sounds, which may cause irreversible speaker damage. Due to its high sound output, do not use it near people or in urban areas with a concentration of noise-sensitive buildings.
